Scala Programming: Get the character at the given index within the String and print the length of the string
Write a Scala program to get the character at the given index within a given String. Also print the length of the string.
Sample Solution:
Scala Code:
object Scala_String {
def main(args: Array[String]): Unit = {
var str = "Scala Exercises!";
println("Original String = " + str);
// Get the character at positions 0 and 10.
var index1 = str.charAt(0);
var index2 = str.charAt(10);
var index3 = str.charAt(15);
// Print out the results
println(s"The character at position 0 is ${index1}");
println(s"The character at position 10 is ${index2}");
println(s"The character at position 15 is ${index3}");
println(s"Length of the string: ${str.length}")
}
}
Sample Output:
Original String = Scala Exercises! The character at position 0 is S The character at position 10 is c The character at position 15 is ! Length of the string: 16
